Series 2000 0w30 (gasoline engine oil)with Amsoil BMK11 by-pass filtration system running a BE 100 1.5 quart filter.
Tested 14 June 04 19,700 miles on the oil and 29,700 on the engine. NO FILTER CHANGES.
Analysis recommendations: No corrective action required, oil is suitable for continued use. Resample at next regular interval.
The first number is my sample at 10,000 on the oil and 20,000 on the engine. The last numbers are the current.
Personal comments are that the oil is starting to degrade now, I'll be changing soon.
To prove a point that the 0w30 hold up well in the TDI engine. Is this oil the best for this engine. Probably not but it does work well, especially with a by-pass filter.
My next plan is to try out the 10w40 AMO. In my opinion this is probably the best overall oil for the engine. Unless you live in the extreme north. I'll be moving to Tennesee, so 10w40 will be good year round. Could I run the new 5w40? Sure, but for less money and as good if not better protection the 10w40 wins out on this test. I'll try for 20K on the oil again to keep the comparison even.
Notice the Silicon level in this sample, for 20K on the oil it's pretty darned good. I'm running the Amsoil Oil wetted foam filter with the snow screen removed. I also like the fact that the Vis has changed very little on this sample between 10 and 20K.
Lastly the TBN is cut in half, I would imagine in another 3,000-4,000 it would be in half again. So there is no way to get 30,000 out of this sample without a filter change. I figure if I'm doing a filter change might as well get it all out of there.
